A Lakeshore OPP officer has been found guilty of dangerous driving causing bodily harm.
Const. Jamie Porto was involved in the crash on Oct. 24, 2014 in St. Joachim.
The SIU report said an officer in an OPP cruiser travelling on County Road 42 collided with a civilian vehicle at the intersection of northbound County Road 31.
The driver of the civilian vehicle sustained serious injuries, including a cracked rib, the court heard in November.
Justice Bruce Thomas told the court on Thursday even if there had been no accident, he would have found Porto guilty of dangerous driving for going 178 kilometres an hour in the 50 km/hr zone in St. Joachim.
He says officers, while appreciated for doing an important job, of responding when someone is in trouble, does not mean they are above the law.
Thomas told the court officers need to be held to the same standard as average citizens with respect to abiding by the criminal code and traffic laws.
Porto's lawyer Dan Scott believes the decision will have a broad impact on policing across Ontario, and how fast officers respond to a call for help.
Porto stayed seated in the courtroom after the case was adjourned and didn't face the 15 people who were here to support him.
Sentencing is set for Jan. 6.
